Python 是一种面向对象、直译式计算机程序设计语言，也是一种功能强大而完善的通用型语言，已经具有十多年的发展历史，成熟且稳定。这种语言具有非常简捷而清晰的语法特点，适合完成各种高级任务，几乎可以在所有的操作系统中运行。详细如下：

Python 3.2 alpha 1 支持 PEP 3147 在 .pyc 目录存放文件，使用 sysconfig 中的模块来访问配置信息，日期时间使用纯 Python 实现。

Python 3.2

Python 3.2 alpha 1 was released on August 1st, 2010.

Python 3.2 is a continuation of the efforts to improve and stabilize the Python 3.x line. Since the final release of Python 2.7, the 2.x line will only receive bugfixes, and new features are developed for 3.x only.

Since PEP 3003, the Moratorium on Language Changes, is in effect, there are no changes in Python’s syntax and built-in types in Python 3.2. Development efforts concentrated on the standard library and support for porting code to Python 3. Highlights are:

numerous improvements to the unittest module
PEP 3147, support for .pyc repository directories
an overhauled GIL implementation that reduces contention
many consistency and behavior fixes for numeric operations
countless fixes regarding string/unicode issues; among them full support for a bytes environment (filenames, environment variables)
a sysconfig module to access configuration information
a pure-Python implementation of the datetime module
additions to the shutil module, among them archive file support
improvements to pdb, the Python debugger
